2. vanessa wants to model how a car's maintenance costs change as the distance someone drives the car increases. what would be an appropriate unit for vanessa's purpose?

miles/$

gallons/miles

$/miles

$/gallons

The answer is $/Miles

Step-by-step explanation:

If Vanessa wants to know hoy the car's maintenance costs change as the distance increases, she is analysing the cost of maintaining the car (wich is expressed in dollars , $), when the distance increases (which is measured in miles or metres, or some other distance measure).Then, the appropiate units of measure for this problem are dollars (to represent the cost of maintenance) and miles (to represent the distance the car travels).

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
